New posts aren't showing up

For the past two weeks new posts don't show up on my website. I followed the posting guidelines, there are no special characters in file names and I also see the posts in the API Browser, but not on the live page. What could be the problem? Thank you for your help.

Hello @g.koncz, welcome to the community. We've answered a similar question recently:

This usually happens when your project is statically built. When you make changes to your documents, create, update, or archive, you need to rebuild your project for these changes to appear.
Do you have access to your codebase and the deployment service?
